Leptopecten
Taxonomy
Leptopecten was named by Verrill (1897) [Sepkoski's age data: T Mi-u-l R Sepkoski's reference number: 1112]. It is extant.
It was reranked as Pecten (Leptopecten) by Oldroyd (1925) and Jordan and Hertlein (1926); it was reranked as Chlamys (Leptopecten) by Grau (1959); it was reranked as Aequipecten (Leptopecten) by Berry (1968).
It was assigned to Pecten by Oldroyd (1925) and Jordan and Hertlein (1926); to Chlamys by Grau (1959); to Aequipecten by Berry (1968); to Chlamydinae by Woodring (1982); to Aequipectini by Coan et al. (2000); to Pectinidae by Moore (1984), Ward and Blackwelder (1987) and Todd (2001); and to Pterioida by Sepkoski (2002).
